Embodiment 1

[0051] A motor assembly 100 for a fan, comprising: a stator 110 , a rotor 120 and an oil retainer 130 . Wherein, at least a part of the stator 110 is disposed inside the rotor 120 . The oil deflector 130 includes a mounting portion 131 and a first shielding portion 132 connected to the mounting portion 131, the mounting portion 131 is connected to the first end of the stator 110, the first shielding portion 132 extends from the mounting portion 131 to the outer surface of the rotor 120, to cover a part of the outer surface of the rotor 120 . There is a gap between the first shielding portion 132 and the rotor 120 .

[0052] The motor assembly 100 proposed in this embodiment includes a stator 110 , a rotor 120 and an oil retainer 130 . The rotor 120 is sleeved on the outside of the stator 110, and the installation portion 131 of the oil deflector 130 is arranged on the first end of the stator 110, so that the first shielding portion 132 of the oil deflector 130 extends to the...

Embodiment 2

[0057] On the basis of the first embodiment above, it is further defined that the end of the rotor 120 close to the installation part 131 is provided with a first groove 121 , and the opening of the first groove 121 faces the installation part 131 . The stator 110 is provided with a second groove 112 , and openings of the first groove 121 and the second groove 112 are oppositely distributed. The side wall of the second groove 112 away from the center line of the rotor 120 protrudes into the first groove 121 , and there is a gap between the groove wall of the first groove 121 and the groove wall of the second groove 112 .

[0058] In this embodiment, the second groove 112 is provided on the stator 110 by setting the first groove 121 with the opening facing the installation portion 131 at one end of the rotor 120 close to the installation portion 131, and the first groove 121 and the second groove 121 are connected to each other. Openings of the groove 112 are opposite to each o...

Embodiment 3

[0065] On the basis of the first embodiment above, it is further defined that the oil deflector 130 further includes a second shielding portion 133 connected to the mounting portion 131 . An end of the rotor 120 close to the installation part 131 is provided with a fourth groove 123 , and an opening of the fourth groove 123 faces the installation part 131 . The second shielding portion 133 protrudes into the fourth groove 123 and leaves a gap with the groove wall of the fourth groove 123 .

[0066]In this embodiment, the oil deflector 130 also has a second shielding portion 133 connected to the mounting portion 131, and the end of the rotor 120 close to the mounting portion 131 is provided with a fourth groove 123 opening toward the mounting portion 131, so that The second shielding portion 133 extends into the fourth groove 123 . After the oil fume enters the gap between the first shielding portion 132 and the outer surface of the rotor 120 , it needs to turn to enter the ga...

Abstract

The invention provides a motor assembly, a fan and a range hood. The motor assembly comprises a stator, a rotor and an oil baffle piece; the rotor sleeves the outside of the stator; the oil baffle piece comprises a mounting part and a first shielding part, and the mounting part is arranged at the first end of the stator; and the first shielding part is connected with the mounting part and wraps a part of the outer side face of the rotor, and a gap is formed between the first shielding part and the rotor. The first shielding part of the oil baffle piece extends to the outer side face of the rotor to shield a part of the outer side face of the rotor, so that oil smoke can enter the space between the rotor and the stator only after passing through the gap between the first shielding part and the outer side face of the rotor, and can move towards the interior of the motor assembly; and a channel for oil fume to flow into the motor assembly is prolonged, so that the difficulty that the oil fume enters the motor assembly is increased, and the situation that a large amount of oil fume is gathered in the motor assembly to influence normal movement of the motor assembly and normal operation of the range hood using the motor assembly can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a motor assembly, a fan and a range hood. Background technique [0002] The motor of the range hood in the related art has relatively poor sealing performance. After the range hood has been in operation for a long time, the oil fume will enter the interior of the motor and continue to accumulate, affecting the normal operation of the motor. Malfunctions such as smoking. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0004] Therefore, the first aspect of the present invention is to provide a motor assembly. [0005] The second aspect of the present invention is to provide a fan. [0006] A third aspect of the present invention is to provide a range hood. [0007] In view of this, the embodiment of the first aspect of the present invention provides a motor ass...
